#### 4.3.6 Swelling Measurements  
Swelling experiments were carried out by immersing the contextwork samples in large excess of 1-PrNO\({}_{2}\) and n-hexane at ambient temperature. Then, the weight of the samples was measured at predetermined time intervals until the samples reached the equilibrium swelling degree (\(Q_{\rm e}\)). The swelling degrees (\(Q\)) were calculated by the following formula:  
\[Q=(m_{\rm s}-m_{\rm d})/m_{\rm d} \tag{3}\]  
where \(m_{\rm d}\) and \(m_{\rm s}\) are the weight of the dry and the swollen samples at a given swelling time, respectively.
