  An increasing interest in molecular structures whose long term dynamics
resemble those of bistable mechanical systems promotes the search of possible
candidates that may operate as two-state switching units. Of particular
interest are the systems that are capable to exhibit such bistable effects as
spontaneous vibrations, stochastic resonance and spontaneous synchronization.
Previously, in all-atom molecular dynamics simulations it has been demonstrated
that short pyridine-furan springs show these bistable phenomena. In this
article we introduce a coarse-grained model of such springs and investigate the
possibility to observe the bistability effects, such as spontaneous vibrations.
Our findings allow the studies of short pyridine-furan springs at large time an
length scales and open field for further computational research of large
bistable systems.
