Using detailed first principles calculations, we have found a new class of stable organic molecular magnets based on zwitterionic molecules possessing donor, $\pi$ bridge, and acceptor groups. These molecules are organic molecules containing only C, H and N. The quantum mechanical nature of the magnetic properties originates from the conjugated $\pi$ bridge (involving only p electrons) where the exchange interactions between electron spin are relatively strong and local and are independent of the length of the $\pi$ bridge, enabling the easy construction of a molecular magnetic device with specified length.
