Correlation between domain size and charge transport properties in benzothiadiazole–thiophene molecules: insights from nano-focus X-ray scattering and fast scanning chip calorimetry

Abstract

Conjugated compounds including thiophene and benzothiadiazole units are promising candidates for next-generation semiconductor materials. Precise control over morphology and crystal orientation is critical for optimizing device performance. By employing a combination of synchrotron nano-focus X-ray scattering and fast chip calorimetry, a correlation was established between the size of ordered domains formed during isothermal crystallization and charge carrier mobility. These findings highlight the potential of advanced in situ techniques for fine-tuning the electronic properties of organic semiconductors.
