ABSTRACT:
The invention relates to an optically non-linear active waveguiding material comprising an optically transparent polymer and a donor group and acceptor group-containing triphenylcarbinol as a dopant. Said dopants have a high hyperpolarizability and have a charge-transfer absorption band which is about the same as that of their corresponding compounds having only one donor-.pi.-acceptor unit. The triphenylcarbinols were found to display good solubility in polymers. Nitro-functionalized triphenylcarbinols are preferred because of their charge-transfer absorption band at a low wavelength (.lambda..sub.max at about 290 nm). Aldehyde-functionalized calix(4)arenes were also found to have this low wavelength charge-transfer absorption band (.lambda..sub.max at about 270 nm). Triphenyls comprising stilbene donor-.pi.-acceptor units are preferred because of their high hyperpolarizability.
