Abstract: Narrow bandgap n-type small molecules are attracting attention in the near-infrared organic optoelectronics field, due to their easy tunable energy band with a molecular design flexibility. However, only a few reports demonstrate narrow bandgap non-fullerene acceptors (NFAs) that perform well in organic solar cells (OSCs), and the corresponding benefits of NFA photodiodes have not been well investigated in organic photodetectors (OPDs). Here, the ultra-narrow bandgap NFAs CO1-4F, CO1-4Cl and o-IO1 were designed and synthesized for the achieved efficient near-infrared organic photodiodes such as solar cells and photodetectors. Designing an asymmetrical CO1-4F by introducing two different ?-bridges including alkylthienyl and alkoxythienyl units ultimately provides an asymmetric A-D?-D-D?-A molecular configuration. This enables a delicate modulation in energy band structure as well as maintains an intense intramolecular charge transfer characteristic of the excited state.

Abstract: Low-coherence enhanced backscattering (LEBS) spectroscopy is an angular resolved backscattering technique that is sensitive to sub-diffusion light transport length scales in which information about the scattering phase function is preserved. Lens-based and lens-free fiber optic LEBS probes are described that are capable of measuring optical properties of a target tissue through depth-limited measurements of backscattering angles within the enhanced backscattered cone.

Abstract: The devices, methods, and systems of the present disclosure provide for spectroscopic super-resolution microscopic imaging. In some examples, spectroscopic super-resolution microscopic imaging may be referred to or comprise spectroscopic photon localization microscopy (SPLM), a method which may employ the use of extrinsic labels or tags in a test sample suitable for imaging.
