TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The compound has ammonium portion and a hydrogen bond is formed with respect to the ammonium portion in the self-accumulated state. The organic compound is formed by inducing a compound containing tetrathiafulvalene analog site in the skeleton and containing protonic acid functional group, to a salt with ammonia or hydroxylamine. Alternately, The organic compound is formed by inducing a compound containing tetrathiafulvalene analog site in the skeleton and containing primary amine to an inorganic acid salt. The organic compound is chosen from compounds of formulae (1-13). The organic semiconductor compound has pseudo closed-shell arrangement.X1-X4=sulfur or selenium;R1=-COO-.NH4+, -COO-.NH3OH+, -CH(CH3)NH3+.BF4-, -CH(CH3)NH3+.Br-, -CH(CH3)NH3+.I-, -CH(C2H5)NH3+.Br-, -CH(C2H5)NH3+.I-, -CH(C2H5)NH3+.BF4-, -C(C2H5)(CH3)NH3+.BF4-, -C(C2H5)(CH3)NH3+.Br- or -C(C2H5)(CH3)NH3+.I-;R2-R8=groups of formulae (i-iii);n=5-10;n'=3-8;andn"=7-12. SPECIFIC COMPOUNDS - The organic semiconductor compound is chosen from 5-ethyl-2,2'-bi-1,3-benzodithiole ammonium tetrafluoroborate of formula (I), ammonia salt of tetrathiafulvalene-2-carboxylic acid, 5-ethyl-2,2'-bi-1,3-benzodithiole ammonium bromide and hydroxylamine salt of tetrathiafulvalene-2- carboxylic acid (all claimed).    EXAMPLE - Tetrathiafulvalene (in g) (1.014) dissolved in dry diethyl ether (100 ml) and lithium diisopropylamide were stirred for 15 minutes. The obtained precipitate was filtered, washed with diethyl ether and dissolved in alkaline water. The aqueous layer was made acidic with 3M hydrochloric acid and extracted with diethyl ether. The organic layer was separated and dried to obtain tetrathiafulvalene 2-carboxylic acid (0.8023) as red solid. The obtained acid (150 mg) was dissolved in dry diethyl ether (30 ml) and filtered. Ammonia aqueous solution was added to the filtrate and solid was deposited. The deposited solid was filtered and washed with diethyl ether. Toluene was further added and ammonia salt of tetrathiafulvalene 2-carboxylic acid (130.8 mg) was obtained with yield of 82%.
