Unique characteristics of a single polymer chain with the effects of stiffness and charge are discussed. It has been well established that a flexible polymer chain undergoes a continuous transition from an elongated coil to a compact globule, corresponding to the transition between disordered gas-like and disordered liquid-like states. Here, we will show that a semiflexible chain exhibits a discrete transition from coil to compact states, corresponding to a disorder-order transition to an ordered crystalline state. We will propose a novel strategy to obtain various kinds of nano-ordered structures from single chains connecting a pair of chains of different stiffness. We will also discuss the effect of charge, putting emphasis on intramolecular segregation in a single polyelectrolyte chain.
