Dipole reversal in Langmuir-Blodgett films of an optically nonlinear dye and its effect on the polarity of molecular rectification / G. J. Ashwell, B. J. Robinson, M. A. Amiri, D. Locatelli, S. Quici, D. Roberto. - In: JOURNAL OF MATERIALS CHEMISTRY. - ISSN 0959-9428. - 15:39(2005), pp. 4203-4205. [10.1039/b506765k]
Abstract:
Langmuir-Blodgett (LB) films of isomeric donor-(π-bridge)-acceptor molecules with either a hydrophobically substituted acceptor [D-π-A-C 16H33 (1)] or donor [A-π-D-C16H33 (2)] exhibit second-harmonic generation and asymmetric current-voltage characteristics: a reversed polarity for rectification arises from an inversion of the dipole orientations in the two types of monolayer.
