Doping of semicrystalline conjugated polymers: dopants within alkyl chains do it better

Autor: Massimiliano Comin, Vincent Lemaur, Andrea Giunchi, David Beljonne, Xavier Blase, Gabriele D’Avino

Publikováno v: Journal of Materials Chemistry C. 10:13815-13825

Electronic structure calculations unveil structure-property relationships in doped polymers: dopants inserted in the alkyl chains are stronger electron acceptors than those in conjugated backbones, leading to integer charge transfer complexes.

Visualizing a Single-Crystal-to-Single-Crystal [2+2] Photodimerization through its Lattice Dynamics: An Experimental and Theoretical Investigation

Autor: Andrea Giunchi, Lorenzo Pandolfi, Tommaso Salzillo, Aldo Brillante, Raffaele G. Della Valle, Simone d'Agostino, Elisabetta Venuti

Publikováno v: Chemphyschem : a European journal of chemical physics and physical chemistry. 23(12)

In homogeneous solid-state reactions, the single-crystal nature of the starting material remains unchanged, and the system evolves seamlessly through a series of solid solutions of reactant and product. Among [2+2] photodimerizations of cinnamic acid

Publikováno v: Crystal Growth & Design. 18:4869-4873

We show that the development of highly accurate density functional theory calculations coupled to low-frequency Raman spectroscopy constitutes a valid method for polymorph characterization alternative/complementary to X-ray. The method is applied her

Publikováno v: Crystal Growth & Design

A method for structure solution in thin films that combines grazing incidence X-ray diffraction data analysis and crystal structure prediction was presented in a recent work (Braun et al. Cryst. Growth Des.2019, DOI: 10.1021/acs.cgd.9b00857). Applied
