Control　of　the　dissymmetry　of　circularly　polarized　luminescence　(CPL)　is　intriguing　and　has　great　potential　for　applications　in　the　field　of　optics.　The　traditional　control　strategy　involves　using　the　opposite　enantiomers　to　achieve　reversal　of　CPL　signs.　However,　regulating　CPL　reversal　by　controlling　only　the　transition　dipole　moments　without　changing　molecular　or　supramolecular　chirality　remains　a　challenge.　Herein,　we　developed　a　couple　of　crystal　materials　based　on　axially　chiral　aggregation-induced　emission　luminogens　(AIEgens).　These　materials　exhibit　achiral　solvent-induced　CPL　sign　inversion　with　identical　helical　structures　and　molecular　chirality　in　their　crystalline　states.　(R)-BPAuCzT　displays　(+)-CPL　with　a　dissymmetry　factor　of　luminescence　(glum)　value　of　+9.81　x　10-4　(560　nm),　while　(R)-BPAuCzC　exhibits　(-)-CPL　with　a　glum　value　of　-1.02　x　10-3　(560　nm).　Time-dependent　density　functional　theory　calculations　show　that　the　magnetic　and　electric　transition　dipole　moments　at　S1　-＞　S0　of　the　(R)-BPAuCzC　unit　cell　are　considerably　influenced　by　the　cocrystallized　solvent　molecules,　revealing　a　solvent-induced　CPL　inversion　mechanism.　The　nonbonding　interactions　between　the　solvent　molecules　(i.e.,　tetrahydrofuran　or　CDCl3)　and　AIEgens　in　the　crystal　play　a　crucial　role　in　the　manipulation　of　the　transition　dipole　moment　of　these　crystal　materials.　Moreover,　microrods　of　(R)-BPAuCzT,　(R)-BPAuCzC,　and　(R)-BPAuCzDCE　exhibit　optical　waveguide　properties　with　relatively　low　optical-loss　coefficients　of　187.3,　567.4,　and　65.2　dB/cm,　respectively.　These　findings　can　help　in　developing　a　new　strategy　toward　controlling　CPL　signals　and　providing　a　potential　application　for　future　integrated　photonic　circuits.
