Fluorescence ofp-N, N-dimethylaminobenzonitrile incorporated in pores of molecular sieves.
The donor-acceptor-substituted aromatic moleculep-N, N-dimethylaminobenzonitrile (DMABN) is known to show a characteristic dual twisted intramolecular charge transfer (TICT) fluorescence with a pronounced solvent dependence. Despite the two-band structure of the fluorescence from DMABN incorporated within pores of the molecular sieves AlPO-5, SAPO-5, ZSM-5, and silicalite, there is no indication for TICT-state emission.
