摘要
空气中制得的N—廿二烷基吡啶嗡-四氰基喹喏二甲烷(NDP-TCNQ)LB膜的横向电导率可达4×10^(-3)S·cm^(-1),其紫外～可见光谱及红外光谱与NDP-TCNQ复合物LB膜的谱图十分相似.小角X-射线衍射结果表明膜有较好的层状结构.对膜在碘蒸气作用下的电导率随时间的变化亦进行了初步探讨.
LB films of N-docosylpyridinium-tetra-cyanoquinodimethane(NDP-TCNQ) formed in air exhibited lateral conductivity of 4×10-3S·cm-1. The UV and IR spectra resembled those of NDP-TCNQ complexes LB films. The films possessed layered structure as revealed by small-angle X-ray diffraction experiment. Temporal evolution of the conductivity of the films upon interaction with the iodine vapor was studied.
