Abstract:
Eight donor–π–acceptor (D–π–A) compounds employing triphenylpyrrole isomers (TPP‐1,2,5 and TPP‐1,3,4) as donors, malononitrile (CN) and 1 H ‐indene‐1,3(2 H )‐dione (CO) as acceptors, pyridone (P) and benzopyran (B) as π‐linking groups were synthesized. The compounds exhibited aggregation‐induced emission and piezochromic properties. Compared with previously reported donors, triphenylpyrroles induced all the compounds to have more remarkable photophysical properties. The compounds containing TPP‐1,2,5 and P moieties displayed stronger fluorescence intensities, shorter emission wavelengths, and more distinct piezochromic properties. However, the same phenomenon was observed in the TPP‐1,3,4‐containing system if B was as π‐linker. Moreover, the CN acceptor endowed the compound to have a relatively strong fluorescent intensity, in which CO induced a relatively long emission wavelength. That is, the photophysical properties of D–π–A compounds can be controlled by adjusting the structure of donor, linker and acceptor.
