(orcid)0000-0002-8932-9085 High hole mobility and light-harvesting in discotic nematic dendrimers prepared: Via 'click' chemistry 2019 Access copy available to the general public Unrestricted We report a new family of liquid crystalline porphyrin-core dendrimers with coumarin units at the periphery of the dendrimer. These compounds have been prepared by copper-catalyzed azide-alkyne "click" cycloaddition (CuAAC). The mesomorphic properties have been investigated via polarized optical microscopy (POM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The peripheral coumarin units play a key role in the liquid crystal behavior, contributing to the appearance of discotic nematic mesophases with hole mobility values among the highest values reported for discotic liquid crystals (of the order of 1 cm 2 V -1 s -1 ). It has also been demonstrated that excitation of the coumarin moieties leads to energy transfer (antenna effect) to the luminescent porphyrin core. Therefore, this strategy, which involves ''click'' chemistry, has been proven to be a powerful and elegant synthetic tool for the preparation of optoelectronic materials based on complex dendritic architectures. info:eu-repo/grantAgreement/ES/DGA-FSE/E47-17R info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2015-70174-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 7.059 2019 PHYSICS, APPLIED 21 / 154 = 0.136 2019 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 47 / 314 = 0.15 2019 Q1 T1 1.934 2019 Materials Chemistry 2019 Q1 Chemistry (miscellaneous) 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Termine, R.
