This work presents a Raman based approach for the rapid identification of the molecular conformation in a series of new 2,3-thienoimide capped quaterthiophenes, whose crystal structures were determined by synchrotron radiation X-ray powder diffractio

Thioindigo (2-(3-Oxo-1-benzothiophen-2(3H)-ylidene)-1-benzothiophen-3(2H)-one) is a synthetic dye related to the natural compound Indigo. Notwithstanding the interest aroused recently by its employment as a functional material in a number of applicat

Indigo [2,2′-bis(2,3-dihydro-3-oxoindolyliden)], a commonly used natural dye, has been shown to exhibit a highly promising semiconducting behavior, allowing for the realization of ambipolar devices. Nevertheless, up to date, it is still unclear whi

We present a rationalization of the solid state behaviour of 1,1,4,4-tetraphenyl-1,3-butadiene (TPB), a well-known blue luminescent molecule, which retains its emissive properties in the solid state. The crystal structures of four polymorphs and one

We present the temperature evolution of polarised Raman and IR reflectivity spectra of Tetrathiafulvalene–Chloranil (TTF–CA) in the lattice phonon region (10–200 cm −1 ). Quasi Harmonic Lattice Dynamics (QHLD) calculations prove to be essenti

We report a high-pressure optical study of pentacene by Raman, absorption, and reflectance spectroscopy. Two modifications, denoted C and H, were used as starting material. Raman spectra indicate a sluggish phase transition of the polymorph C to the

We have recently studied two solid phases of bulk pentacene (polymorphs H and C) by means of lattice phonon Raman spectroscopy. The assignment, previously based on lattice dynamics calculations alone, is now verified by X-ray diffraction measurements

We report for the first time lattice phonon Raman spectra of pentacene measured by means of a Raman microprobe technique. We experimentally prove the existence of two polymorphs, as expected from recent structural studies. A comparison with Quasi Har

In this paper we discuss an algorithm for calculation of the temperature-dependent anharmonic correction to the phonon spectrum in atomic and molecular crystals. We show how the equation of motion method can be used to compute corrections of arbitrar

Raman phonon spectra of the quasi-linear crystal 1,4-dibromonaphthalene (DBrN) have been recorded as a function of temperature (ambient pressure) and in the pressure range 0–12.5 GPa at room temperature. No phase transition has been detected up to
