中心对称萘酞菁分子的LB膜及其聚集特性研究

研究了三种中心对称的萘酞菁分子LB膜的制备及其聚集特性。三种萘酞菁化合物均能制成很好的LB膜。在稀溶液中，四叔丁基萘酞菁以单体为主要存在形式;对四叔丁基萘酞菁锌，由于金属锌原子的作用，在稀溶液中不仅能形成H-聚集体，而且还能形成J-聚集体，且主要以聚集体的形式存在。在LB膜中，这两种化合物均形成了H-聚集体。对于双四叔丁基萘酞菁铒不论在稀溶液中还是在LB膜中均主要以单体的形式存在。

Studies on Properties of Aggregates and Langmuir-Blodgett Films for Centrosymmetric Naphthalocyanine Molecules

Deposition of Langmuir-Blodgett films and the aggregative properties of three centrosymmetric naphthalocyanine derivatives were investigated by using linear absorption spectra. Good LB films could be formed for all the three compounds. In dilute solution, the monomers are the main formation for the tetra-tert-butyl-cyan naphthalocyanine. Due to atomic zinc action, the tetra-tert-butyl ~naphthalocyanine zinc molecules could not only form H-aggregates, but also form J-aggregates. The tetra-tert-butyl naphthalocyanine zinc molecules mainly are aggregates in dilute solution. In the Langmuir-Blodgett films, both tetra-tert-butyl-cyan naphthalocyanine and tetra-tert-butyl-cyan naphthalocyanine zinc formed H-aggregates. The monomers are the main formation for the bi-(tetra-tert-~butyl -naphthalocyaninato)-orbium in dilute solution and Langmuir-Blodgett films.
