title: [Studies on properties of aggregates and Langmuir-Blodgett films for centrosymmetric naphthalocyanine molecules].
abstract: 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-tertbutyl-naphthalocyaninato)-orbium in dilute solution and Langmuir-Blodgett films.
