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