π-Conjugated molecules provide new material insights for next-generation semiconductor technologies geared for a new era based on the inherent advantage that the optoelectrical properties of π-conjugated molecules can be easily tuned by molecular orientation and aggregate forms. In this presentation, we propose that self-organized multiscale structures of π-conjugated molecules are an attractive candidate for realizing novel organic semiconductor devices. The polycrystalline nature of π-conjugated molecules with intrinsically random distribution spanning the nanoscale and microscale makes them an excellent entropy source for physically unclonable functions that have emerged as built-in cryptographic primitives of hardware-based authentication digital key generation. In addition, the strategy of molecular design and self-assembly process to implement a coiled coil-like nanohelix of π-conjugated molecules with strong chiroptical activities will be introduced for a chiral optoelectronic device.
