    We developed a series of blue-emitting 1,8-naphthalimide dyes covalently attached to 2-(2-hydroxyphenyl)-2H-benzotriazoles that retard photodegradation of the fluorophore. The dyes displayed weaker fluorescence emissions than the parent 1.8-naphthalimide. Quantum chemical calculations suggested that the decreased fluorescence was caused by the nonradiative deactivation promoted through the excited state intramolecular proton transfer (ESIPT) in benzotriazole components. The dyes' phosphorescences in a degassed solution at 77 K were more efficient than that of the parent 1.8-naphthalimide, indicating a possible deactivation pathway through intersystem crossing. PMMA films doped with these dyes showed higher resistance against photoaging than the film doped with an equimolar mixture of constituent 1.8-naphthalimide and the benzotriazole derivatives. Thus, the covalently linked benzotriazole units slow fluorophore degradation not only by preferential absorption of harmful UV light, which is found in the film with a simple mixture of two components, but also by the nonradiative deactivation involved in benzotriazole units.

    Exciton interactions are not only observed in assembled molecules but also in compounds with multiple chromophores referred to as superchromophores. We have developed isomeric bis-squaraine dyes as superchromophores in which two squaraine chromophores are fused onto the isomeric benzodipyrrole skeleton so as to regulate conformations and to reduce distances between two chromophores. The dyes with benzo[1,2-b:3,4-b’]dipyrrole and benzo[1,2-b:5,4-b’]dipyrrole moieties exhibited split electronic absorption originated from the intramolecular exciton interaction. The intensity of the split absorption bands varies in correlation with the orientation of chromophores. The isomeric dye with benzo[1,2-b:4,5-b’]dipyrrole moiety exhibited a near-infrared absorption associated with the resonance throughout two chromophores. Their electrochemical and spectroelectrochemical properties are distinct from those of monomeric dyes owing to electronic interactions between the two chromophores. Thus, the structural isomerism of the central skeleton significantly affects their optical properties as well as their electrochemical properties.

    A series of group 14 element bridged bithiophene dimers bearing dicyanovinyl (DC) or thiobarbiturylmethylene (TB) electron-withdrawing groups at the molecular termini (series E-1a and series E-1b; E = C, Si, and Ge) were developed as red absorbing singlet oxygen (1O2) photosensitizing dyes. These dyes exhibited broad and strong absorption in the red-to-deep red regions and efficient red-to-NIR fluorescence (photoluminescence quantum yield phi PL; 0.32-0.45 in dichloromethane). The terminal TB groups led to more red-shifted electronic absorption and fluorescence emission than the DC groups, owing to more intense intramolecular charge transfer. The 1O2 generation photosensitization abilities of series E-1a and series E-1b were evaluated by the 1,3-diphenylisobenzofuran method, and large 1O2 generation quantum yields (phi Delta) were obtained upon irradiation of 630 nm light, ranging from 0.35 to 0.68 in dichloromethane. Therefore, these dyes show fluorescence properties as well as 1O2 generation photosensitization ability. Introduction of bromo groups at the 3,3 '-positions in Si-1a and Si-1b afforded the new potential photosensitizers Si-2a and Si-2b that accompanied blue-shifted electronic absorption as well as blue-shifted fluorescence emission with the low phi PL. Unfortunately, as Si-2a exhibited quite low absorptivity in the red region, 1O2 generation photosensitization with 630 nm light was not evaluated for Si-2a. On the other hand, Si-2b showed significantly efficient 1O2 generation photosensitization upon irradiation of 630 nm light (phi Delta; 0.88). Considering the result of theoretical calculations showing that the bromo groups effectively contribute to the frontier orbitals, these bromo substituents should facilitate the intersystem crossing from the excited singlet state to the triplet excited state through the strong spin-orbit coupling.

    © 2020 Elsevier Ltd Near-infrared (NIR) emitting functional dyes have been attracting considerable attention because they are useful in the fields of cellular imaging, security application, energy conversion, and so on. In this study, to develop NIR fluorescent dyes with high photoluminescence (PL) quantum yields (ΦPL), novel acceptor–donor–acceptor (A–D–A) type π-conjugated molecules have been prepared, where dimeric dithienosilole (DTS) and freebase or quaternized 1-pyridylacryronitrile are involved as the D and A moieties, respectively. The freebase dye exhibited red fluorescent emission at 654 nm with ΦPL of 0.10 in dichloromethane at rt, whereas the methylation of the pyridine moieties at the molecular termini led to a significant red shift of the emission to the NIR region (PL maximum λPL; 822 nm), accompanied by improvement of a high ΦPL of 0.20 in dichloromethane at rt. The results of density functional theory (DFT) and time-dependent DFT calculations indicated that the considerable red shift of the emission band of the quaternized dye originates from effective intramolecular charge transfer from the DTS donor to the terminal pyridiniums and that the high value of ΦPL is brought about by minimal structural relaxation upon photoexcitation. NIR emission was also obtained when the freebase dye was placed under acidic conditions: protonation at the Lewis basic pyridine moieties brought about halochromic response of PL to yield red-shifted emission (λPL; 755 nm), when trifluoroacetic acid was added to the dichloromethane solution.

    In this paper, thienylpyridinium-cyclic enolate betaine (TPB) dyes were reported as unique skeletons of fluorescent donor-acceptor type molecules. TPB derivatives with five-membered cyclic enolates are coplanar because of the intramolecular hydrogen bond formation between the carbonyl oxygens of the cyclic enolate and the α-hydrogens of the pyridinium ring. However, a six-membered cyclic enolate leads to a pre-twisted structure due to the steric hindrance. TPB derivatives with alkylene-bridged cyclic enolates exhibited obvious fluorescence quenching through the twisted intramolecular charge transfer (TICT) process in solution. In contrast, electron-deficient cyclic enolates suppressed the TICT process, and thus relatively intense emission was observed. This report also discusses deactivation processes in the excited state of each TPB derivative by theoretical calculations to support the experimental results. These observations present a rational design strategy to control the TICT of TPB derivatives.

    © 2019, © 2019 Taylor & Francis Group, LLC. Novel starburst-type triphenylphosphine oxide trimers PO-1 and PO-2 were synthesized aimed at application as an electron-transporting material for multilayer organic light-emitting diodes (OLEDs). They showed high glass transition temperatures (Tg; 175 and 205 °C, respectively) and high lowest triplet energies (T1; 2.81 and 2.78 eV, respectively). Their high solubility in 2-propanol allowed us to fabricate multilayer OLEDs by solution processing, and a double-emitting layer OLED consisting of poly(9-vinylcarbazole)-based p-type and PO-1-based n-type layers doped with a phosphorescent material (FIrpic) showed efficient sky-blue electroluminescence with a maximum external quantum efficiency of 9.33%.
