Abstract:
A phenylacetylene compound represented by the following general formula (1), ##STR61## wherein A.sup.1 to A.sup.12 each independently represent a hydrogen atom, a fluorine atom, or an alkyl group having 1 to 10 carbon atoms, and at least one is an alkyl group (provided that, in A.sup.1 to A.sup.12, the cases are excluded where both of A.sup.1 and A.sup.2 are methyl groups at the same time, while the others are hydrogen atoms, and where both of A.sup.7 and A.sup.12 are methyl groups at the same time, while the others are hydrogen atoms); R.sup.1 and R.sup.2 each independently represent a fluorine atom, a cyano group, a 4-R.sup.3 -(cycloalkyl) group, a 4-R.sup.3 -(cycloalkenyl) group, or a R.sup.4 --(O).sub.q group (where R.sup.3 represents a hydrogen atom, a linear or branched alkyl group having 1 to 12 carbon atoms which may be substituted by fluorine, a linear or branched alkenyl group having 2 to 12 carbon atoms which may be substituted by a fluorine atom, or a linear or branched alkynyl group having 2 to 12 carbon atoms which may be substituted by a fluorine atom, and R.sup.4 represents a linear or branched alkyl group having 1 to 12 carbon atoms which may be substituted by a fluorine atom, a linear or branched alkenyl group having 2 to 12 carbon atoms which may be substituted by a fluorine atom, or a linear or branched alkynyl group having 2 to 12 carbon atoms which may be substituted by a fluorine atom; and q represents 0 or 1):, provided that the compound is not ##STR62## wherein n is 1 to 12.
