Highly ordered monolayer assemblies of phthalocyanine derivatives

Abstract

Monolayer assemblies of several phthalocyanine derivatives, e.g. copper tetrakis(n-butoxycarbonyl)phthalocyanine, showing highly anisotropic absorption spectra have been obtained.

Two-dimensional “nano-ring and nano-crystal” morphologies in Langmuir monolayer of phthalocyaninato nickel complexes

“…Because alkoxy chains grafted on the Pc ring are not polar enough to anchor the macrocycle parallel to the water surface. The macrocycles are thus tilted with respect to the water surface, and able to self-organize into columnar assemblies [44][45][46]. The big difference on the orientation angles of 1 and 2 suggests that the size of the substituents at α position significantly affect the conformation of phthalocyanines at the air-water interface, which is not observed for the β substituted phthalocyanines.…”

High speed layer by layer patterning of phthalocyanine Langmuir–Blodgett films by the atomic force microscope

“…21,22 Some samples have thus been annealed 2 days at 110°C in order to prepare anisotropic films. 21-23, these films consist of stacked monolayers with a columnar ordering of the molecules within each layer, and an interlayer distance of 2.1 Ϯ0.1 nm.…”

Synthesis, electrochemistry and in situ spectroelectrochemistry of novel hexadeca-substituted phthalocyanines with three different groups

“…These unique properties lead to many applications in different scientific and technological areas such as photoconducting agents in photocopying devices, chemical sensors [4], catalysis [5], liquid crystals [6], photodynamic therapy of cancer [7,8], solar energy conversion [9], nonlinear optics [10], semiconductors [11], and optical data storage [12].…”
