  Molecular self-assembly is a well-known technique to create highly functional nanostructures on surfaces. Self-assembly on two-dimensional (2D) materials is a developing field driven by the interest in functionalization of 2D materials in order to tune their electronic properties. The functions of some natural supramolecular architectures, such as ribosomes, are dependent on the recognition of different types of chiral biomolecules. However, the recognition of different types of chiral molecules (multiobject chiral recognition), such as amino acids and sugars, by independent and identically artificial supramolecular assembly, was rarely achieved.

Polymer preparation. The preparation of PPM(TOAA) was carried out as follows: to a solution of TOAA (0, mmol, as template) in dichloromethane ( μL) were added phthalocyanine 1 ( mmol, as the first functional monomer) and MAA ( mmol, as the second functional monomer) in a glass adding of EGDMA ( mmol, as cross-linker) and AIBN ( mmol, as initiator. 3. Self-Assembly of Polymeric Dyes. In living cells, self-organization directs and regulates specific reactions, often at very dilute concentrations, while competing with a myriad of other possible reactants without physical barriers [].Nature achieves this multifarious task by using dynamic molecular recognition to sort reactive centers according to inherent molecular codes, and augmenting.

Octa- and tetra-alkylthio substituted phthalocyanines are typical p-type semiconductors and the introduction of four Cl, Br, or I atoms lowers frontier orbital energies by only up to eV and.   This book assimilates this information, using recent advances from the study of phthalocyanine-based materials to critically evaluate their potential role in emerging technologies. Following a brief historical overview and a chapter devoted to chemical synthesis, the book describes the various types of molecular and polymeric phthalocyanine Author: Neil B. McKeown.

This book assimilates this information, using recent advances from the study of phthalocyanine-based materials to critically evaluate their potential role in emerging technologies. Following a brief historical overview and a chapter devoted to chemical synthesis, the book describes the various types of molecular and polymeric phthalocyanine 5/5(2).

The syntheses of a novel 1,4,8,11,15,18,22,octahexyloxy-2,3,9,10,16,17,23,octa-(4-trifluoromethoxyphenyl) phthalocyanine (3a) and its zinc(II) phthalocyanine derivative (3b) have been described and characterized by elemental analysis,1H NMR, 13C NMR, 19F NMR, mass, UV-Vis and FT-IR.

This micro-review presents an overview of molecular materials derived from phthalocyanines which are substituted with crown ether rings. These flat disk-like molecules can self-assemble into ordered, well-defined structures with or without the aid of alkali metal by: Phthalocyanines (Pcs) are commonly applied to advanced technologies such as optical limiting, photodynamic therapy (PDT), organic field-effect transistors (OFETs), and organic photovoltaic (OPV) devices, where they are used as the p-type layer.

An approach to Pc structural diversity and the incorporation of a functional group that allows fabrication of solvent resistant Pc nanostructures. In this work, novel dendritic zinc phthalocyanines showing both molecular NIR fluorescence and aggregation-induced emission characteristics have been successfully synthesized via a two-step reaction on the basis of bisphthalonitrile precursors with different electron donor–conjugation–acceptor (D–π–A) structures.
