摘要: Reversible morphological changes occur with photoisomerization of azobenzene in Langmuir–Blodgett (LB) films complexed polycations, which contradicts an implicit assumption the concept free volume that two-dimensional film structures are preserved during photoisomerization. J-aggregates chromophores formed by two processes. The first process is “light-induced J-aggregation” photoisomerized molecules form J-aggregates. other “triggered J-aggregation,” one components triggers J-aggregation another chemical species mixed films. Both processes many cases accompanied large However, LB fabricated using under isobaric conditions do not change their morphology light-induced and patterned ultraviolet illumination through a photomask. Phase separation gives rise to patterns, used fabricate templates amphiphilic silane-coupling agent as Nanopatterns also fabricated. © 2007 Japan Chemical Journal Forum Wiley Periodicals, Inc.
