“…3b). The α ′ value is lower than some recently reported in optical waveguiding organic crystals 42–44 and on the order of the best derivatives reported recently by our research group 45 and by others. 46 It is known that the excellent crystallinity improves the exciton-photon coupling and the migration of excitons, favouring the light transmission process.…”

“…The calculation of the OLC was carried out through the equation I=I 0 e À αx , where I is the PL intensity in the output, I 0 in the input, x is the propagation distance in the crystal and α the parameter to determinate in μm À 1 (Figure 7b). After conversion α to dB μm À 1 (by using the relation α (dB μm À 1 ) = 4.34 α (μm À 1 )), the value calculated for OLC is 1.13×10 À 2 dB μm À 1 , that is in the order of the best derivatives reported, [38][39][40] corroborating the good efficiency of this optical waveguide.…”

In order to achieve a multifunctional compound with potential application in organic photonics and electronics, a multidonor benzothiadiazole derivative was rationally designed and synthesized employing microwave irradiation as energy source, increasing the process efficiency about yields and reaction times in comparison with conventional conditions. This powerful compound displayed solvatochromism and showed efficient behavior as red optical waveguide with low OLC around 10‐2 dB μm‐1 and with the capacity of light transmission in two directions. In addition, the proposed derivative acted as efficient p‐type semiconductor in organic field‐effect transistors (OFETs) with hole mobilities up 10‐1 cm2V‐1s‐1. This corroborates its multifunctional character, thus making it a potential candidate to be applied in hybrid organic field‐effect optical waveguides (OFEWs).

A series of donor‐π‐acceptor‐π‐donor (D‐π‐A‐π‐D) compounds based on naphthalendiimide (NDI) and perylenediimide (PDI) central cores combined with triphenylamine and phenylcarbazole donor groups have been synthesized, characterized and tested in top‐contact/bottom gate organic field‐effect transistors (OFETs). The results showed high electron mobilities, up to 0.3 cm2 V−1 s−1, in the case of NDI derivatives and moderate values of around 10−3 cm2 V−1 s−1 for PDI‐based semiconductors. Quantum chemical calculations were performed in order to support the experimental data. The results suggest that adequate molecular characteristics and larger crystalline domains in NDI vs. PDI semiconducting films may be the reasons behind the enhanced electrical properties of NDI derivatives. Furthermore, when the lateral donor substituents are triphenylamine groups, the mobilities were slightly higher in comparison to phenylcarbazole donor groups due to an improved electron‐donating character. Other characterization techniques, such as AFM, X‐ray diffraction or spectroelectrochemistry, among others, have been performed to analyze supramolecular order, charge carriers’ nature and stability, parameters closely related to charge transport characteristics.

New insights into structure/optical waveguide behavior relationships in linear bisethynylbenzenes

Abstract: In order to establish a relationship between the structure and the optical waveguiding behavior, two series of linear bisethynylbenzenes combining trifluoromethyl and methoxy groups in the core and external rings were synthesized.
