Photochromism: Molecules and Systems by Heinz Durr, Henri Bouas-Laurent. (Photoactive cyclophanes 5) The 1H NMR (Figure 10 and Supporting Information p S2) and the 13C NMR spectra ( 52 distinct signals are observed, see Experimental) point to the absence of symmetry in the molecule. Direct access to: 10 most recent · Browse issues The effect of pressure on photochromic furylfulgide is investigated using monodispersed molecules in solution and molecules in a single crystal by measuring the optical absorption at room temperature under pressure provided using a diamond anvil cell. To achieve higher resolution than conventional optical imaging would allow, we will employ an innovative approach called absorbance modulation (AM), in which a layer of photochromic molecules is placed on top of the photoresist.6 The photochromic molecules squeeze the diameter of the light transmitted into the photoresist. The researchers predict that the new semiconducting thin film, with its molecules that have electrically and optically tunable states, could lead to a variety of semiconducting systems. An organic thin-film transistor with the new semiconducting layer. The hybrid material consists of two photochromic molecules that can be quickly switched between two states with a laser.

Reversible intramolecular photocycloaddition of a bis(9-anthrylbutadienyl)paracyclophane – an inverse photochromic system. Photochromism: Molecules and Systems. An optical-lithography system employs independently focused light beams for manufacturing custom semiconductors. Download Photochromism: Molecules and Systems. Photochromism is simply defined as the light induced reversible change of colour. Image credit: an additional layer of photochromic molecules apart from the semiconducting layer.
