摘要：

Freshly deposited Langmuir-Blodgett films of Z-beta-(N-n hexadecyl-2-benzothiazolium)-alpha-cyano-4-styryldicyanomethanide, C16H33-BT3CNQ, have a sharp intramolecular charge transfer (IRCT) band at 568 nm and a broad intermolecular (INCT) band at 652 nm. Annealing causes the IRCT absorbance to increase from 0.007 to 0.012 per layer and second harmonic generation (SHG) at 532 nm to be significantly enhanced by the proximity of this band.
