Optical Index Matching, Flexible Electrospun Substrates for Seamless Organic Photocapacitive Sensors

Planar, rigid glass substrates support the formation of organic small-molecular semiconductor thin films with extended crystalline texture and distinct pleochroism (top in cover picture), visible by cross-polarized microscopy. Woven, soaking electrospun nanofiber mat disrupt growth, leading to submicron-sized crystallites embedded fiber mesh (bottom). The benefits tissue-like mats are that they become virtually transparent wet, physiological environment. Therefore, considered Timo Grothe, Andrea Ehrmann co-workers (article number 2000543) as alternative for future visual all-organic neuro-prosthesis.
