Abstract:	Based on Darboux transformation, we firstly generate breather solutions sitting on zero background via module resonance for complex modified KdV equation. Then some novel molecules, breather molecules and breather-soliton molecules, are obtained theoretically by module resonance and velocity resonance. Further, we study the higher-order b-positons with zero background on the basis of degenerate Darboux transformation and module resonance for first time. We discuss the dynamics of higher-order b-positons in detail and propose related propositions. Finally, we find new elastic interactions between smooth positons and b-positons by means of degenerate Darboux transformation and partial module resonance
