An organic semiconductor includes: a compound represented by formula (I): 

Organic semiconductor, photoelectric conversion element and image device

A photoelectric conversion device is provided and includes a photoelectric conversion layer containing a compound represented by the following formula (1). Formula (1):  In the formula, Zrepresents an atomic group for forming a 5- or 6-membered nitrogen-containing heterocyclic ring; Za represents an atomic group for forming a 5- or 6-membered ring; Rrepresents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group or a heterocyclic group; Lto Leach represents a methine group which may have a substituent or may form a ring with another methine group; p1 represents 0 or 1; n1 represents an integer of 0 to 4 and when n1 is an integer of 2 or more, each Lor Lmay be the same as or different from every other Lor L; M1 represents an ion for neutralizing the electric charge; and m1 represents a number necessary for neutralization of the electric charge; provided that a compound where Zis an atomic group forming a thiazoline nucleus or a thiazole nucleus is excluded.

Photoelectric conversion device, imaging device and photosensor

A merocyanine dye is provided. The merocyanine dye is represented by formula (1). In the formula (1), Arepresents a divalent atomic group, n represents an integer of 1 to 3, Aand Aeach independently represent an aromatic hydrocarbon ring or a heterocyclic ring having 3 to 18 carbon atoms, and Rand Reach independently represent a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, an aryl group having 6 to 18 carbon atoms, or a heterocyclic group having 3 to 18 carbon atoms.

Merocyanine dye and photoelectric conversion device

A radiation imaging devicehas a phosphor film; a photoelectric conversion portionincluding an upper electrode, a lower electrode, and a photoelectric conversion filmdisposed between the electrodes; a signal output portionincluding a field effect thin film transistorhaving an active layerformed from an amorphous oxide and that outputs a signal corresponding to electric charges generated by the photoelectric conversion portion; and a substrateon which the signal output portion, the photoelectric conversion portion and the phosphor film are formed in this order. Each of pixel portions is made up of the signal output portion, the photoelectric conversion portion and the phosphor film, and the signal output portion and the photoelectric conversion portion in each of the pixel portions are formed so as to have an overlapping portion in a thickness direction.
