A thiophene compound having a phosphate group, for example, one represented by the formula [1]. The compound has high resistance to heat and oxidation and can be improved in solubility or dispersibility in various solvents. (In the formula, Rand Reach independently represents, e.g., hydrogen, halogeno, cyano, or phenyl optionally substituted by W; and Rto Reach independently represents &#x2014;OR, SR, or &#x2014;NR, provided that Rto Reach independently represents hydrogen, Calkyl, or phenyl optionally substituted by W and W represents halogeno, cyano, nitro, hydroxyl, mercapto, amino, formyl, carboxy, Calkyl, etc.)

A thiophene compound having sulfonyl groups which is represented by the formula [1]. It has high heat resistance and high unsusceptibility to oxidation and can improve solubility and dispersibility in various solvents. [In the formula, Rand Reach independently represents hydrogen, halogeno, cyano, etc.; and Rand Reach independently represents Calkyl, Chaloalkyl, phenyl optionally substituted by W, thienyl optionally substituted by W, etc. (W represents chlorine, etc.).]
