Herein, a homologous series of compounds with even\u2010numbered carbon chains from <jats:italic>n<\/jats:italic>=4 to 18 were synthesized, in which \u2212Cl was substituted for \u2212CH<jats:sub>3<\/jats:sub> at the kink position and a drastic modification in the phase structure of the bent\u2010shaped molecule was observed. An unusual stabilization of the cubic blue phase (BP) over a wide range of 16.4\u2009\u00b0C has been witnessed. Two homologues in this series (<jats:bold>1<\/jats:bold>\u201012 and <jats:bold>1<\/jats:bold>\u201014) exhibit an interesting phase sequence consisting of BPI\/II, chiral nematic, twist grain boundary, smectic\u2005A, and smectic\u2005X (SmX) phases. The higher homologues (<jats:bold>1<\/jats:bold>\u201016 and <jats:bold>1<\/jats:bold>\u201018) stabilize the SmX phase enantiotropically over the entire temperature range. Crystal structure analysis confirmed the bent molecular architecture, with a bent angle of 148\u00b0, and revealed the presence of two different molecular conformations in an asymmetric unit of compound <jats:bold>1<\/jats:bold>\u20104. A DFT study corroborated that the \u2212Cl moiety at the central core of the molecule led to an increase in the dipole moment along the transverse direction, which, in turn, facilitated the unusual stabilization of frustrated structures. Crystal polymorphism has been evidenced in three homologues (<jats:bold>1<\/jats:bold>\u201010, <jats:bold>1<\/jats:bold>\u201012, and <jats:bold>1<\/jats:bold>\u201014) of the series. On the application of mechanical pressure through grinding, compound <jats:bold>1<\/jats:bold>\u201010 transformed from a bright yellow crystalline solid to a dark orange\u2013green amorphous solid, which reversed upon dropwise addition of dichloromethane, indicating reversible mechanochromism in this class of compounds. In addition, excellent thermochromic behavior has been observed for compound <jats:bold>1<\/jats:bold>\u201010 with a controlled temperature\u2013color combination.<\/jats:p>","DOI":"10.1002\/chem.201905707","type":"journal-article","created":{"date-parts":[[2020,2,21]],"date-time":"2020-02-21T09:27:51Z","timestamp":1582277271000},"page":"5859-5871","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Chiral
