Thereby advancing the development of actuators, light\u2010melt adhesion, and photolithographic technologies. In this study, we designed a series of acid\u2010assisted molecular salts that precisely direct the reactive olefin\u2010pairs into the prerequisite geometry required for [2+2] photoreaction. The neutral 3\u2010ThPy (3\u2010ThPy =\n                    <jats:italic>E<\/jats:italic>\n                    \u2010(3\u2010Thienyl)vinyl\u20104\u2010pyridine) (\n                    <jats:bold>1<\/jats:bold>\n                    ) is photo\u2010inert in the solid state as the olefin\u2010pairs are separated by 6.28 \u00c5 exceeding Schmidt's criteria. However, protonation with different acids resulted in the head\u2010to\u2010tail (HT) alignment of the olefin moieties, primarily driven by cation\u00b7\u00b7\u00b7\u03c0 interactions.
